STACK ER.

SPECIFICATION forming part of Letters Patent No. 715,232, dated December 2, 1902.

To a/ZZ totorn t may concern: f

Be it known that I, GEORGE WASHINGTON YVORLEY, a citizen of the United States, and a resident of Goldlield, in the county of Wright and State of Iowa, have vinvented a new and Improved Stacker, of which the `following is va full, clear, and exact description.

This invention relates to a ymechanism for carrying off the straw and chad/from threshing-machines and stacking the same at any desired adjacent point.

This specification is a specific descriptionA of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, formin'ga part of this specification, in which similar characters of reference indi cate corresponding partsin all the views.

Figure l is a sectional side elevation of the invention. Fig. 2 is a rear elevation with parts broken away. Fig. 3 is a sectional plan view thereof on the line 3 3 of Fig. 1. ,'Fig. t is a section on the line 4 4 of Fig. l, and Fig. 5 is a detail view of gearing for swinging the chute.

a represents the strawrack of the harvester, and a the sieve over which the chad and grain are passed to separate them from each other. The straw-rack o terminates in a pan 0.2, which is tapered toward the rea-r end and over which is arranged the drum b, which carries a number of radially-disposed rak'es c, arranged to move into and ont of the drum as the drum turns. carried in gangs by bars c within the drum and sliding in radial slots b' in the heads of the drum. The bars o extendl parallel with the axis of the drum and project outside thereof, carrying rollers c2 at their ends.

o3 indicates rings eccentric tothe axis of the drum and held rigidly by arms c4. These rings are engaged by the rollers c2, and by the joint action of the rings c`3 and the centrifugal force of the drum the rakes are caused to move in and out of the drum as the same revolves. The rakes serve to gather the straw as it passes from the rackand to carry it-over the pan o2 and upward into the passage d.

The drum b is mounted on a shaft b2 and is drivenLby a belt e, which connects it with a drive-shaft f. The drive-shaft carries two fans f', which are arranged, respective1y,.in

These rakes are Application ned February 6.1902. serai No. 92,773. (No man.;

boxes a3, formed on the casing of the harvester, at the rear thereof. These boxes as converge into each other, and the passage d forms aV continuation of the fan-boxes. The

rfan-bores draw in the chaif from the sieve a vreceive the straw therefrom. This elbow is held to turn in a collar g2, fastenedon the harvester at the top thereof and provided with a number of antifriction-sheaves g3, bearing against the collar to allow it to turn easily. Wound around the base of the elbow g' is a 7o cord or wire h, which is also woundiaround a small sheave 7i', .fastened on a vertical shaft h2, mountedin the casing of the harvester. This shaft h2 is provided at its lower end with a beve1-gear h3, in mesh with a corresponding 75 gear t' on a shaft i' within the harvester alongside the drum b, but passing transversely to the axis thereof-that is to say, the shaft b. The shaft b carries a worm b2, and this is in mesh with a worm-wheel i2 on the shaft t. 8o The shaft b also carries a spur-wheel b3, in mesh with a spur-wheel k on a shaft 7o', passing across the shafti' parallel with the shaft b. The shaft k carries a vworin 152, in mesh with a worm-wheel 3 on the shaft 11'.. The 85 worm-wheels i2 and 'i3 are loose on the shaft t" and have clutch-faces formed on the sides ad- .jacent to each other. With these clutch-faces works a clutch Z, splined on the shaft t" and connected with a lever l', so as to'be moved 9o from one position to the other. By means of this gearing the shaft 2f may be driven from the shaft b in either direction, and thus theY shaft h2, with the elements h and h, may be driven in either direction, as desired. This wili swing the chute g so as to deliver the straw and chaff in the'position desired. The chute gis sustained in horizontal adjustment,

as shown, by means of a .connection g4, passing to the chute from a suitable device for roo supporting the latter. This connection g4, which may be a wire or a rope, passes to a truss g5 on the chute, as illustrated. The nn-v der side of the chute at its discharge end is cut away, as indicatedat fm, to give the chute the cross-sectional form best shown in Fig. 1I.

Arranged to slide on the chute g, at the cutaway point thereof, is a chute-section n,which is semicircular in cross-section and which may be moved outward to ll the portion cut away at m. This sliding section n may be moved outward or inward, as desired, so that the chute may be continued unbroken to the front extremity thereof, or by moving the section n inward the chute may be allowed to dump the straw at any point desired. The section 'n has a strap 'n' fastened thereto to facilitate its adjustment, and this adjustment may be made either manually or by any desired device provided for this purpose. This sliding section n works with a collapsible hood, which when in operative position causes the straw to drop from the desired point on the chute. The hood comprises a rigid circular segmental section 0 and several folding circular segmental sections o', these folding sections having intel-engaging edges to prevent them from moving out beyond the position shown. Connected with the sections 0' of the hood are tailpieces 02, which strike one another in the closing operation, so as to move the sections o and o together. The several sections of the hood may fold into each other, with the section o lying outside of all.

p indicates a frame to which the section 0 is rigidly fastened and to which the sections o are pivoted. This frame is located outside the chute and is held to slide on a frame p', carried on top of the chute g.

p2 indicates a rope passed around a sheav p3, whereby to slide the frame and bodily move the hood.

q indicates a lever fulcrumed at its middle coincident with the axis of the pivots of the hood-sections o' and fastened to said pivots. This lever is adapted to be thrown to open or close the hood by ropes q', connected with its ends.

By drawing inward the section n and adjusting the hood in open position near the outer end of said section the straw may be dropped short of the outer end of the chute. By folding the hood together and running out the section 'n the straw may be carried to the very end of the chute.

The `operation of the invention is as follows: The drum l), turning rapidlyand working with the rings c3, throws the takes c outward over the pan a2 and causes them to move over the same to draw the straw from the pan and force it into the passage CZ. The blast from the fans f passes from the boxes a3, drawing with it the chaff. All of this matter is thus forced out through the passage d into and through the chute. The straw and cha may be dumped at any place-desired by swinging the chute and adjusting the slid- .ing section fn and hood o.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of myinvention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.
